Abstract

Ag(Pd) bimetallic nanostructures (Ag(Pd)NPs) were synthesized using the galvanic replacement of palladium ions with silver nanoparticles. Based on a comparative analysis of the results of scanning electron microscopy, energy dispersive X-ray microanalysis, and X-ray powder diffraction, it was established that the obtained Ag(Pd)NPs can be considered as “core-shell” nanosystems, in which the core is silver, and the shells are palladium nanoparticles with a size of 5–15 nm. Ag(Pd)NPs were studied as catalysts for the aerobic liquid-phase oxidation of benzyl alcohol. The addition of Ag(Pd)NPs to the reaction system accelerates the reaction in 14 times.

银（钯）双金属纳米粒子的合成与催化特性

利用银纳米粒子电化学置换钯离子的方法合成了Ag(Pd)双金属纳米结构（Ag(Pd)NPs）。根据对扫描电子显微镜、能量色散 X 射线显微分析和 X 射线粉末衍射结果的比较分析，确定所获得的 Ag(Pd)NPs 可视为 "核壳 "纳米系统，其中核为银，壳为尺寸为 5-15 纳米的钯纳米粒子。研究将 Ag(Pd)NPs 作为催化剂用于苯甲醇的有氧液相氧化。在反应体系中加入 Ag(Pd)NPs 可使反应速度加快 14 倍。
